## Description

Extra Size for Safety

Review: I bought this HUANCHAIN 20 ft white extension cord to use with my TV, and it’s been excellent so far. The cord feels very high quality—thick, durable, and not flimsy like cheaper options. I like that it’s flexible and doesn’t get stiff, making it easy to route behind furniture. The length is perfect for reaching the outlet without stretching or tangling. The white colour blends in nicely and doesn’t stand out. Overall, this is a well-made, reliable extension cord and definitely worth it for powering a TV setup.
Review: This is a nice quality cord that was perfect length for my needs. I wanted a flat plug outdoor cord to plug in roof heat cable to a smart plug on my outdoor out box. I needed the box lid to close to protect it from the snow and this is going to work perfectly. It was hard to find a shorter length cord and one with a flat plug. I have it connected but haven’t used it yet so all can say it is it looks like a nice quality cord and it fit my needs perfectly.
